If the transmission oil leaks out of left side half shaft area, it may be from a worn axle shaft seal. The seal can be damaged by a poor surface finish on the axle shaft. The axle shaft and seal should be replaced to correct the problem.

Mercury Mariner Reviews
Had the mariner for 7 months now and I am really pleased with it. The V6 has plenty of pep for me and I really like the 30+ miles per gallon. I like the visibility and the head room. Tried a chevy equanaux and could not get in without bumping my head. I had a 03 mariner and it was about the same but not as good gas mileage. I think I will stick with mariners.
2008 Mercury Mariner - I have had my car for 6 years, over 108,000 miles and have never had a single problem with it. It still rides great. I have never had to have the breaks replaced, not even the battery. Nothing leaks and the Sewell Ford dealership in Odessa, TX has the best service of any dealership I have ever used. They are the very best.
Bought my 2007 Mercury Mariner LX V6 4WD, used in 2009, with 24,000 miles. For the first year, I believed I had made a good purchase, however having to replace brakes (pads and rotors turned) at 30,000 miles. I didn't give this a second thought as the brakes may have never before been serviced. Then at 37,000 miles I had to replace them again. At 44,000 I had to replace the rotors, as well. The car "eats" brakes. OK, so now we're at 71,000 miles. The transmission has gone and needs to be replaced. $4,000.00 bill. No car should require a new transmission at 70,000 +/- miles. I had owned a Ford Bronco (1986 V8, 4WD, Eddie Bauer Edition - purchased brand new) that was such a mechanical-failure-nightmare, I swore I'd never buy another Ford product again in my lifetime. Well, I bought the Mercury Mariner (first Ford failure... shame on them; second Ford failure... shame on me), and my vow has been re-established. Never again will I buy a Ford product. I've had three Jeeps and not so much as a single major repair. I have now had two Fords and they are nothing but mechanical headaches. No wonder the Japanese, Germans, and Koreans are taking over the auto industry, huh? They build quality and reliability. Something the American car makers don't understand.
I have about 140,000 miles on my car. This has been a great investment. The only problem I am having now are; the oxgyen sensors are bad. I am having a hard time trying to replace it. This has been an excellent buy. I am very happy I purchased this car.
When I purchased the vechicle, I was told the everything was 100% in good working condition. The vechicle only had 32,000 miles on it. 2 days after I purchased the Mariner, I tried the front defrost switch and there was no heat whatsoever. I called the dealer and they said that they didn't know if the heater problem was covered in the warranty. I checked the heater hoses at the fire wall and both were hot, this lead me to believe that this vechicle had front end damaged and the heater control for the AC/heater vent door was not reconnected. At this time according to the dealer that the A/C section of the box was warrantied but the heater section is not. Does anyone have any knowedge or ideas to help me with this delemlia.......... contact me at . thank you..........
